If you think the waits at airport security are bad now, just wait until summer.
That's the warning from American Airlines, the latest in a growing chorus of Transportation Security Administration critics who say the agency isn't doing enough to make sure passengers make their flights.
"The lines at TSA checkpoints nationwide have become unacceptable," American spokesman Ross Feinstein said in a statement Wednesday. "The result: our customers are waiting in TSA lines greater than one hour."
And the problem got "exponentially" worse in the first three months of the year, normally slow times for air travel, he said.
During the spring-break week of March 14-20, nearly 6,800 American passengers missed flights because of checkpoint delays, with the worst cases occurring in Los Angeles, Miami, Atlanta, Dallas and Philadelphia.
"As we approach spring and summer, we are concerned that these lines will grow even longer," Feinstein said.
